    It's really simple to recaulk a lead and oakum joint. You will need to rent inside and outside caulking irons, (see image) The iron with the outside bevel you will take your hammer and, using medium light hits, work around the inside of the lead joint. The iron with the inside bevel you will do the same on the outside of the joint. That's all there is too it. The lead joint will be compressing the oakum and your leak will be history. Number#1 iron has no bevel. No's 2 & 4 are inside irons and 3 & 5 are outside irons. Good luck, Tom
